php-cp(php-connect-pool),redis和pdo的本地代理

[中文简介] http://blog.sina.com.cn/s/blog_9eaa0f400102v9fd.html

提供连接池,读写分离,负载均衡,慢查询日志,大数据块日志等功能

要求

  • PHP 5.3 + (no zts)
  • linux 2.6+
  • pdo and redis extension install

安装

  • phpize && ./configure && make install
  • echo "extension=xx/connect_pool.so" >> php.ini

使用Docker安装

可以使用Docker编译,需要在项目的根目录下运行:

  1. 根据自己的配置,复制 php.ini.example 文件为 php.ini 文件,修改 pool.ini 文件
  2. docker build -t php-cp .

技术特性:

  • 提供了release方法,在每次fetch数据后(redis的get set) 调用,将连接放回到池子里面,避免其他耗时操作导致的db层连接数过高问题。
  • 提供最大最小连接数配置支持。
  • 连接自动ping 数据库, 防止压力小长时间不请求导致的gone away问题
  • 根据压力自动获取(最大到最大连接数)或者释放(释放最小到最小连接数)池子里面的连接。
  • 做了大量优化虽然请求经过代理进程转发但基本没有性能损耗.
  • 当池子里面的连接被占用没了,接下来的挣钱连接的进程将会排队,直到持有连接的进程release连接.
  • 使用透明化,相对于传统的pdo和redis操作,只需要修改new的类名,以及适当时机release连接即可(可以集成到db层框架)
  • 支持pdo的读写分离和从库的负载均衡。
  • 支持cli模式下的pdo和redis异步查询。
  • 支持慢查询日志(max_hold_time_to_log)以及大的数据块(max_data_size_to_log)日志功能。

提示

  • 请求结束(rshutdown/mshutdown阶段)会调用自动调用release,不要依赖于这个release,否则连接利用率会很低
  • 关于异常: pdoProxy和原生Pdo不一样的一点是 默认pdo是静默模式 不抛异常 pdoProxy是抛异常的(且是用Exception类抛出的 不是PDOException)
  • pool_server 必须以root用户启动
  • redis不支持pub/sub方法
  • 当你用完一个连接后(例如:fetchAll调用结束),请调用release来马上释放连接到池子里面(如果事务需要在事务commit或者rollback后release),如果不想改业务代码可以在框架层每次fetch(或者get/set)用完之后调用release方法。

集成好的框架

使用

  • 将项目中的pool.ini文件mv到/etc/pool.ini,并根据需求修改配置文件
$ mv ./pool.ini.example /etc/pool.ini
$ chmod +x ./pool_server //pool_server为php脚本 可自行修改
$ mv pool_server /usr/local/bin/
  • 日常运维使用
$ pool_server start //启动服务 如果配置文件的daemonize开启则后台运行 否则为前台运行 Ctrl+c结束服务
$ pool_server stop //停止服务
$ pool_server restart //重启服务
$ pool_server status //查看服务状态
  • 日常开发使用
    将该项目源码加入IDE的外部库中, 即可有代码提示, 切记不要加入php配置的include path中
